App Store Freezing When Downloading

Unmounting the Boot Camp partition worked for me also.

Unmounting and remounting the Bootcamp partition worked like a charm, thanks a lot everyone!

I too had the spinning beachball problem. After unmounting the Bootcamp partition, trying to install an app gives this error.
"There was an error in the App Store. Please try again later. (@@errorNum@@)".
Could be just server trouble though.

iMac & MacBook Pro have bootcamp.
MBP didn't have problem with Mac App Store (didn't have to unmount bootcamp).
On the other hand iMac had problem (freezing when downloading). Unmounted bootcamp and the problem was solved.

Possible reason (unconfirmed): iMac has NTFS-3G installed and MBP doesn't.

My question is: Do you have NTFS-3G (or similar program that lets you read & write on ntfs partition)?

Hi,

Yep exact same issue - trying to download an app or go to updates it beachballed over and over.

Unmounted my boot camp partition works fine now.

And yep Barkane, have NTFS write on the bootcamp partition - so you could be on to something there..

Confirmed: I had the same problem. I ejected the bootcamp partition and it worked just fine.

Confirmed, disable enable boot camp. I bought Aperture tried to start it, and it did not show up, disabled boot camp partition again, started aperture now it works. Enabled bootcamp still worked.
Clicked on updates in App Store, app store is freezing, did the bootcamp trick, and it works.
Hope they will fix this fast, annoying problem!

Sorry folks, but I do not have bootcamp loaded on my machine and still getting error of MZFinance.NoGUIDTokenFailureKey_message. I tried all suggestions and still getting it.

Unmounting my Windows NTFS partition worked for me. Hopefully Apple will patch it up soon!

After a couple of hours of trying on Thursday (reboots and relaunches), the App Store Terms of Service update message appeared and everything proceeded smoothly thereafter.

The App Store is working fine for me now, I agreed to the new iTunes TOS on my iPhone last night and this morning I could download fine (after unmounting Boot Camp), so it could have been the App Store has trouble displaying its TOS agreement.

Similar except I was logged in and downloading an App from the App store and then I updated my iphone apps in iTunes and as soon as I entered my password both cpu's went to 100%, beachball, Mac App stopped downloading, I was unable to Force Quit and eventually I had to power off to restart and clear the problem.
I dont run any VM or Bootcamp.

Just to add the solution that worked for me (similar to migsevilla previously)...

Mine was hanging (beach ball). I had Bootcamp and External Drives, but dismounting them was not a viable long term option. Logging out from my account and then purchasing a random free app eventually, after a minute or two, prompted me for my credentials. I signed back in and then suddenly everything started working normally again.

I'd eliminated network, background processes, and most of the other reported problems over the last hour.

Hope this helps someone else.

Thanks to whoever first suggested unmounting the boot camp partition. But now I'm getting that error with the app store (100) message. lol just one thing after another isn't it.

You'd think Apple would bother doing some QA and debugging before releasing this to the general masses...

Error 100 is related to aunthentication and/or needing to accept tue new terms and agreement EULA. Unfortunately the AppStore does not tell you this or give you the chance to do this automatically other than the very first time the program is opened (on a per user account basis).

Fix:
Open the AppStore, sign out of it, quit the AppStore.
Open iTunes, attempt to buy a new App; just download a free one that you have never downloaded. Now it should force to accept the new EULA terms and agreement. Accept, and if you need to attempt to buy/download the app again, otherwise let it download completely then quit iTunes.

Open the AppStore, go to download something and it should ask you to sign in and this time actually work.
